Tumor metastasis remains the major cause of cancer-related death, but its molecular basis is still not well understood. Here we uncovered a splicing-mediated pathway that essential for breast cancer metastasis. We show RNA-binding protein heterogeneous nuclear ribonucleoprotein M (hnRNPM) promotes by activating switch alternative splicing occurs during epithelial–mesenchymal transition (EMT). Genome-wide deep sequencing analysis suggests hnRNPM potentiates TGFβ signaling and identifies CD44...
Adenosine deaminases acting on RNA (ADARs) are the primary factors underlying adenosine to inosine (A-to-I) editing in metazoans. Here we report first global study of ADAR1-RNA interaction human cells using CLIP-seq. A large number CLIP sites observed Alu repeats, consistent with ADAR1's function editing. Surprisingly, thousands other located non-Alu regions, revealing functional and biophysical targets ADAR1 regulation alternative 3' UTR usage miRNA biogenesis. We observe that binding UTRs...

Accurate prediction of protein-ligand binding affinity is important for lowering the overall cost drug discovery in structure-based design. For accurate predictions, many classical scoring functions and machine learning-based methods have been developed. However, these techniques tend to limitations, mainly resulting from a lack sufficient energy terms describe complex interactions between proteins ligands. Recent deep-learning can potentially solve this problem. search more efficient...
The epithelial–mesenchymal transition (EMT) is a fundamental developmental process that abnormally activated in cancer metastasis. Dynamic changes alternative splicing occur during EMT.
